To all whom it may concern:

Be it' known that I, N1-Liman SHURTLEFF, a citizen of the United States, and a resident of hloline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in .Fuel-Feeding Devices, vof which the' following is a specification. p

My invention relates to a fuel feeding device adapted particularly for controlling the feed of oil to'carbureters ,of vehicle gas engines where the carbnreter'is above the level of the oil supply tank.

Among the important objects of the invention are to produce a device Iof this class comprising only a few simple parts which will eiiiciently coperate to control the feeding; to canse a common container to act both as a iioat and for receiving and storing fuel to be fed to the carbureter while the main container is being refilled; to provide i1nproved means yfor -preventingwavering or hesitating movement of the float-container member and to cause positive and quick action thereof and movement to its eXtreme positions to quickly actuate valve mechanism for controlling the relling of thema-in container, recharging of the storage container,

,and the connection with the containers of the outlet with which the carbureter is connected, my improved means operating magnetically; to provide construction and arrangement which'will enable the device to' be readily taken apart for inspection, repair ,or cleaning purposes; and in general to provide a simple, inexpensive and highly eflventV leakage.

cient device of this class.

On the accompanying drawing I show a device which embodies the various features of my invention. On this drawing n Figure 1 is a vertical diametral sectional view of the device,.and

Fig. 2 is a top view thereof.`

The outer or main container 5 is formed by the cup-shaped halves 6 and 7 tted together edge to edge and secured by means of opposedlugs or flanges 8-and 9 and bolts 10, a suitable gasket 11 being interposed to pre- The upper half has the threaded opening 12 for receiving piping 13 which carries oil from a supply tank (not shown) and which in the yvehicle issituated below the level of the carbureter. In order to strain `the fuel before entering the oontainer a screen 141s. secured at its bottom and side edges to the inside of the container in front of the inlet l2 and with its top edge.

spaced away from the container wall in order that if the screen should become tainer is the threaded boss 15v in which is secured th'e'iittingy 1G from which a pipe 17 extends up axially into the container 5, the outer end of the tting being threaded to receive a coupling cap 18 v'for securing a pipe 19 which leads to the carbnreter not shown) Within the main container 5 is the cylindrical member 2O which serves both as a float and as a storage container for fuel. The member is preferably formed by cylindrical cup-shaped halves 21 and 22 secured and sealed together at their edges. At the center of its lower wall the member 2O has the boss 23 whose opening 24 receives the pipe 17 already referred to, the container 2.0 being slidable on this pipe. Just above the fitting 16 the pipe 17 has port holes 25 which, when the containerV 2O is down, are open only to such container, and when the container is up the ports are open to the outer container 5.

Extending downwardly from the upper wall of the container 20 is a pipe 27 and seated and secured in the upper end of this; pipefis a pln'g 28 in which the lower end of the hollow valve stem 2,9 is secured, the container 20 being at all times open to the atmosphere through this stem. Fitted in the top of the container 5 at the center thereof is a. block 30 having the cylindrical valve passageway 31 through which the stem 29 extends. The block has the internally threaded lug 32 extending therefrom for receiving a pipe which leads to the manifold of the vehicle engine (not shown). The interior of the lug is connected by la ne passageway 33'witli the valve passageway 31. Near its upper end the valve stem has the enlarged cylindrical section 34 which forms a valve, the lower edge 35 of this valve being preferably tapered as shown in order that `the-valve may readily reenter the passage- The container halves can be in roe Leccese auxiliary reservoir is e decided improvement over prior structures in which the reservoir und iioet are separate members.

My improved device can therefore be inexpensively manufactured and kept in perfect condition with little lafbor and expense.
